i3 (std & graber) Ramp board fan cooling holder

This is my simple fan holder to cool the ramp or other controller board.

And it just sit on and clamped into the side frames. use a double adhesive tape also will work

easy t adjust the position by sliding it upward or downward

Fan i use is ROUND FAN with 9,5cm diameter. BUT any other fan is can be used

Enjoy
